HORSE-POWER.

SPECIFICATION forming part of Letters Patent No. 340,938, dated April 2'], 1886.

Application filed January 11, 1886. Serial No. 188,184.

T 0 all whom it may concern.-

Be it known that I, GEORGE W. CRANE, a citizen of the United States, and aresident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain Improvenients in HorsePowers, of which the following is a specification.

My invention relates to improvements in horse-powers that are applicable for general use, but are especially adapted for elevator purposes.

The invention consists, general-1y, in the construction and combination hereinafter described, and particularly pointed out in the claim. I

In the accompanying drawings, forming part of this specification, Figure l is a sectional side elevation, and Fig. 2 is an end elevation, of a machine embodying my invention.

In the drawings, A represents the sills of the frame. To these sills are secured the upright posts or standards 13. A cross beam, 0, is secured to the upper ends of the standards B. The standards B and cross-beam O are se curely braced by the diagonal rods D, Whose upper ends are spiked or bolted to the beam 0, and whose lower ends are spiked or bolted to the sills A. A cross-sill, E, extends across the frame upon one side of the posts B, as shown in Fig. l.

Fis an upright shaft whose upper end passes through a box, S, that is secured to the side of the crossbeam O, and whose lower end is seated in a step, G, that is located on the top of the sill E, upon the top of this shaft the sweep-head is fastened by any suitable means.

The horizontal master-wheel H is mounted upon the shaft F. This wheel is made of large size and extends nearly to the sides of the frame.

I is a horizontal shaft whose inner end is journaled in a box, K, that is fastened upon the sill E. The outer end of the shaft is journaled in a box, L, that is secured to the top of the sill A.

J is a bevel-pinion on the shaft I,thatmeshes (No model.)

with the master-wheel H. As the master wheel is of large size, it is necessary to hold it firmly upon the pinion J. For this purpose I provide an arched bridge-tree, M, that is se cured to the frame A, which is formed with a sleeve or collar, B, through which passes a stud, S. Upon this stud is mounted anidler, N, that bears upon the upper surface of the master-wheel directly over the pinion J. The shaft I passes under the arch of the bridgetree, as shown in Fig. 2. This shaft is coupled to a tumbler-rod, O, by a universal joint, P.

By locating beam Oand sill E with relation to each other as shown, it permits the boxes for shafts F and I to be readily put in place and removed when necessary, and simplifies and cheapens the construction. The sleeve or collar R also strengthens the connection of the idler N to the arch. The result of all is that a most efficient horse-power is formed, the parts of which can be readily put up and taken down.

I claim as my invention- The within described horse power, com posed of a frame,A, beam C,braced by bars D, cross-sill E, located with reference to beam O substantially as shown, box S, secured to the side of said beam, step G, secured to the top of said sill, shaft F, carrying master-wheel H andjournaled in said box and step, boxes K and L, secured, respectively, to said sill and frame A, shaft I, carrying pinion J, meshing with the master-wheel and journaled in boxes K and L, the arch M, straddling box L and formed with sleeve R,and thestud S,carrying idler N, to bear on the master-Wheel above pinion J, the said several parts being relatively arranged substantially as shown and described.

In testimony whereof I have hereunto set my hand this 6th day of January, 1886.

GEORGE w. CRANE.
